DRILL-FEED.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed August 3. 1905. Serial No. 272,511.

To all whom, it may concrn:

Be it known that I, JOSIAH G. WINGER, a citizen of the United States, and a resident of Grand Valley, in the county of Warren and State of Pennsylvania, have invented a new and ImprovedDrill-Feed, of which the following is a full, clear, and exact description.

The invention relates to an improved means for feeding or regulating the feed of drills by fluid-pressure. It is especially useful in connection with drills employed for driving wellssuch as oil, gas, and Artesian wellsin which the drill is connected by a rope with means for alternately raising and lowering the drill and devices are provided by which the rope may be gradually lengthened as the drill sinks in the shaft. Heretofore this work was usually done by what is commonly known as a temperscrew, which has been manually operated to feed drills during its operation. The operation of this device is slow and laborious. By means of my invention the drill may be raised by hydraulic action and gradually lowered, the latter operation requiring no exertion whatever.

The invention consists in certain features which will be fully set forth hereinafter and pointed out in the claims.

Reference is had to the accompanying drawings, which illustrate, as an example, the preferred embodiment of my invention, in which drawings like characters of reference indicate like parts in the several views, and in which Figure 1 is a side view of the invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section of the pump. Fig. 4 is a cross-section on the line 4 4 of Fig. 1. Fig. 5 is a detail section on theline 5 5 of Fig. 4, and Fig. 6 is a section on the line 6 6 of Fig. 3.

Referring to Figs. 1 and 2, 10 indicates the walking-beam or other drill-driving element of the well drilling machine. Mounted on the free end of the walking-beam 10 is a cross pin or trunnion 11 of a stem 12, which stem is joined to or formed integral with the head 14 of a fluid-pressure cylinder 15. The cylinder 15 is thus held pendent from the end of the walking-beam, and at its lower end the cylinder is provided with a suitable stuffing-box 16, through which passes the rod 17 of a piston 18, which operates in the cylinder. At

its lower end the rod 17 carries a cross-arm 19 and clamping devices 20, which latter debalance.

vices serve to connect the rod with the drillrope. The cross-arm 19 is joined to two elevating-ropes 21, which pass upward alongfar as possible for the rod 17 to move in the During the drilling operation the cylinder.

parts 17 and 18 and the devices in connection therewith are by means which will be fully set forth hereinafter allowed gradually to drop in the cylinder, thus feeding the drill. When the parts assume the position shown in the drawings, they may be again returned to the starting position, the drill-rope being slacked out to allow for the increased depth of the well.

23 indicates a reservoir the upper end of which is in communication with the upper end of the cylinder 15. The reservoir is mounted alongside of the cylinder and has a pipe 24 passing from its lower end, which pipe leads into the cylinder 15 at the lower part thereof below the lowest position of the piston 18. Said pipe 24 is fitted with two valves 25 and 26, respectively, which may be employed to throttle the fluid-flow through the pipe. Fig. 5 illustrates the valve 26,

which, as here shown, is conical in form and the position of which will enlarge or contract the opening through which the liquid will flow from the cylinder. The pipe 24 has a branch 27, which leads to a pump-cylinder 28. This cylinder is suitably mounted alongside of the main cylinder 15, the branch 27 extending to the upper part of the cylinder, which is formed with an interior enlargement 29, coacting with a corresponding reduction 30 in the diameter of the pump plunger or piston 31. Said plunger is also provided with a chamber 32, communicating with the space formed by the reduced portion 30 through the medium of openings 33. The lower end of the plunger 31 has a valve 34, which permits fluid to pass from the chamber 32 into the space below the plunger, but prevents the return of this pressure. The lower part of the plunger is also provided with a packing 35, which may be of any desired form. The valve 34 is held to its seat by a spring 36, and 37 indicates a perforated plug which is screwed into the lower end of the plunger and engages the spring. In this way upon the downward movement of the plunger the liquid will be drawn into the chamber 32, and upon the upward movement of the plunger the same will be forced past the valve 34 into the lower part of the pump-cylinder 15, where it is compressed by the subsequent movement of the plunger.

38 indicates a pipe passing from the lower part of the pump-cylinder 28 to the lower part of the main cylinder 15, and 39 indicates the valve which commands this passage and prevents the return of fluid into the pump.

The plunger 31 is operated by a link 40, which is connected to the plunger, and an elbow-lever 11, suitably fulcrumed on the machine.

In the use of the invention the parts are adjusted as shown in the drawings. Assuming them to be in the position shown in Figs. 1 and 2, in order to raise the drill the handle should be operated to force the pressure from the pump into the lower part of the cylinder 15, the pump taking the fluid, which is preferably a liquid, from the reservoir by way of the pipe 24 and branch 27. The liquid under pressure entering the lower part of the chamber 15 will raise the piston 18 and the connected parts, including the drill. When the drill has been thus raised, the drilling operation may be begun, and by adjusting the valve 26 and, if desired, the valve 25 the flow of liquid from the lower portion of the cylinder 15 may be throttled, so that any desired length of time will be consumed in the descent of the drill. In this way the drill may be fed as fast as desired. As the fluid gradually escapes from the lower part of the cylinder past the valve 26 and the valve 25, if it is desired to use this valve, the drill steadily drops and the fluid passes through the pipe 24 up into the reservoir 23 and overflows from the upper part of the reservoir into the upper part of the cylinder 15. The reservoir is employed to make up for the difference between the contents of the cylinder 1 5 on the lower and upper sides of the piston, it being clear that the rod 17 on the under side considerably re duces the contents at this point and makes it necessary to provide the reservoir 23, so that all of the liquid which can be contained above the piston 1n the cylinder 15 may be forced out of the upper part of the cylinder as the piston and. its connections are raised. The hydraulic pump 28 may be operated at any time to return the piston, drill, &c., to their upper position. After the piston 18 and its connections descend to the position shown in Fig. 2 the drill-rope should be dis connected from the clamp 20, whereupon the counterbalance on the ropes 21 will lift the piston and rod automatically, and the drill rope may be again fastened in the clamp, so

placing the parts in position for a second op eration. It will be observed that this will involve very little time and labor and enables the drilling-machine to be operated almost continuously.

Having thus described the preferred form of my invention, I claim as new and desire to secure by Letters Patent I 1.
